Apexbio Technology LLC Palifosfamide,5mg CAS# 31645-39-3

Palifosfamide is the active moiety of ifosfamide (IFA) [1].IFA is alkylating agents which are active against a variety of pediatric sarcomas such as rhabdomyosarcoma (RMS), Ewing’s sarcoma (ES), osteosarcoma (OS) and other undifferentiated soft tissue sarcomas [1].In human OS cell lines SaOS-2, OS229 and OS230, Palifosfamide lysine has broad activity with IC50 ranging from 2.25 to 6.75 μM. While OS222 had the IC50 of 31.5 μM [1].In CB17 female SCID mice, palifosfamide lysine (100 mg/kg) administered intravenously for three consecutive days, the mean weight loss was less than 15% and complete recovery to baseline within 4 weeks of treatment. Other sizes are also available. Please inqury us for quote.

Research Products International Corp RPI Cefuroxime, Sodium Salt, 25 Grams

Cefuroxime Sodium Salt is a second-generation cephalosporin antibiotic. Cefuroxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This interference disrupts the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cefuroxime is effective against a wide spectrum of bacteria, both Gram-positive and Gram-negative. In microbiology and research settings, it is sometimes used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Additionally, Its inclusion allows for the specific growth of bacteria lacking resistance to cefuroxime.

AG Scientific Inc Tetracycline HCl 25 G

Tetracycline hydrochloride is a hydrochloride salt form of the antibiotic tetracycline. This polyketide antibiotic binds to both the 30S and 50S ribosomal subunits, thus inhibiting proper protein synthesis. Although it is capable of binding to both subunits, the binding at the 30S subunit is more pronounced than that at the 50S.Clinically, tetracycline is used as a broad spectrum antibiotic for a variety of Gram-positive and Gram-negative bacterial infections. Conditions which may indicate for tetracycline administration include upper respiratory infection, typhus fever and rikkettsialpox. It can also be administered to treat severe cases of acne.Tetracycline has played a prominent research role in studies of the efficacy of local antibiotic application in cases of dental trauma. Owing to the fluorescent properties of tetracycline and its ability to bind to bone tissue, this antibiotic is also regularly used in bone histomorphometry studies.

Medchemexpress LLC HY-111558A 10mg Medchemexpress, Bobcat339 hydrochloride CAS: Purity:>98%

Medchemexpress, HY-111558A 10mg Bobcat339 HCl CAS: Bobcat339 hydrochloride is a cytosine-based TET enzyme inhibitor with IC50 of 33 μM (TET1) and 73 μM (TET2). It is useful to the field of epigenetics and serves as a starting point for new therapeutics that target DNA methylation and gene transcription. The TET enzymes is responsible for catalyzing the reverse process that is DNA demethylation by recognizing 5-methylcytosine and oxidizing the methyl group via an Fe(II)/alpha-ketoglutarate-dependent mechanism. Purity:>98% Medchemexpress has over 10000 novel life-science reagents, reference compounds, APIs and natural compounds for laboratory and scientific use. Other quantity can also be offered.

AG Scientific Inc Hygromycin B in Water, 10 ML

The concentration of Hygromycin B in DI water is 100mg/ml. Hygromycin B is an aminoglycoside antibiotic effective against bacteria, fungi, and eukaryotic cells that are isolated from Streptomyces hygroscopicus. It is composed of amino groups attached to glycosides, that bind the 30s ribosomal subunits. This action causes the mRNA sequence to be misread, resulting in protein synthesis inhibition. Hygromycin B is also an antiviral agent, which works as a standard section antibiotic in gene experiments.CAS Number: 31282-04-09Molecular Weight: 527.5 DaChemical Formula: C20H37N3O13Storage Temperature: +4CResearch or further manufacturing use only, not for food or drug use.
